The 1050 Ti does NOT require a large PSU. I've tested this many times.
I even measured and shared the results using a Watt Meter at:

It shows about a max 173 Watt draw under load.
If you have a HDD in there, that can lead to chop as well. Especially those drives with high values in the SMART registers 01 and 07. I use Speccy to get at those values.
